Product Self-Inspection Steps
- Detect any deviation, slack, or skew in the installation position of the object and proximity sensor, as well as any wiring or connection issues.
- Check for adhesion or accumulation of metal dust.
- Ensure normal usage under temperature and environmental conditions.
- Verify the display lamp type for abnormal flashing.
During inspection, avoid self-disassembly and repair. Use a portable detector to investigate the sensor's operating state for easy fault detection and repair.
Regularly check the photoelectric sensor to maintain long-term stability. Stock replacement sensors to quickly address any issues without disrupting sensor usage.
